Aggregates For the past 2 years, the aggregate industry has mined and sold almost 2.12 billion metric tons of crushed rock, sand and gravel. It is critical to have service trucks ready to keep the heavy equipment needed to move the aggregate materials running, even in the harshest work environments. The service truck bodies must be built to last, but they also have to be highly reliable, functional and safe for the operator, and that’s what Summit Truck Bodies has brought to the table. Summit products that have been in high demand for clients in the aggregate industry include both the medium- and heavy-duty mechanic service truck, as well as the crane truck. Lube skids and lube trailers are also a vital service truck product, as are canopy bodies, fuel and lube combo service truck bodies.
